calories burned during strength training

Use a HRM. I finally broke down & bought one & I love it!

Found this calculation on tumblrgym.tumblr.com

While exercising be sure to take your heart rate a couple times. You only need 10 seconds to figure it out. First make sure you have a clock. For ten seconds count how many heart beats you have in that time and then multiply it by 6 to get your beats per min. Take your heart rate a couple times during your exercise and write it down quickly then add those numbers together and divide them by the number of times you took your heart rate to get an idea of your average exercise heart rate. Then follow this formula to figure out how many calories you burned.

First divide your weight in pounds by 2.2 to convert to kilograms.

_________÷ 2.2 = _________kg

For women multiply your average heart rate during exercise by 0.4472 your weight by 0.1263 and your age by 0.074

_________ beats/min x 0.4472 = A

_________kg x 0.1263 = B

_________years x 0.074 = C

For men multiply your average heart rate by 0.6309 your weight by 0.1988 and your age by 0.2017.

_________ beats/min x 0.6309 = A

_________kg x 0.1988 = B

_________years x 0.2017 = C

Add A + C - B = D

_________ + _________ - _________ = D

Subtract 20.4022 from D and then divide by 4.184 to get the total calories burned per min

( _________ - 20.4022 ) ÷ 4.184 = Calories burned /min

multiply calories burned per min by the number of mins you exercised.

_________cals/min x _________ mins = total amount of calories burned

i agree. i purchased one and i love it!

My HRM shows the calories burned during my weight circuits to be equal or actually more than my cardio workout. A HRM seems to be the way to go.
